This paper presents a method for locating multiple partial discharge (PD) sources based on maximum a posteriori (MAP) estimation. The sensors placed in the monitoring area, such as a substation, receive PD signals and estimate the direction of the arrival angles by using estimation of signal parameters via rotational invariance techniques. Then the sensors send the measurement data to the processing...
This paper presents a locating method for multiple partial discharge (PD) sources based on the maximum a posteriori estimation. The feature of this method lies in monitoring an entire substation. The sensors installed in the monitoring area such as the substation receive PD signals and estimate the direction of arrival angles. Then integrating all the estimated angles provides source positions. The...
